This looks like it was already fixed in Python 3.7:
$ ./python.exe
Python 3.7.0a3+ (heads/master:7f7de371f9, Jan 6 2018, 21:35:03)
[Clang 9.0.0 (clang-900.0.39.2)] on darwin

>>> from dis import dis
>>> def f():
... x = ()
... y = 2, 4
...
>>> dis(f)
2 0 LOAD_CONST 1 (())
2 STORE_FAST 0 (x)
3 4 LOAD_CONST 2 ((2, 4))
6 STORE_FAST 1 (y)
8 LOAD_CONST 0 (None)
10 RETURN_VALUE
